The father has had a history of violence against his own family, and this may not be the first time the baby was abused. Doctors found old blood in the baby’s brain, suggesting he has been abused before.

Clarence Hawkins has been accused of hitting family members five times before, and he’s been charged with aggravated battery.

Hawkins denies causing the brain damage, but admitted to biting the baby.

In the criminal complaint, the baby’s 5-year-old sibling told police, “Daddy hates the baby. Daddy hits him on the back and hits him in the face.”

While the father sits behind bars, the mother has a restraining order against him, banning him from contacting her or their other children.

At 5 p.m. Monday, the baby remained in critical condition at University of New Mexico Hospital.
